Unable to create listing in US, but works in other regions

I have successfully created the listing in the GB and DE regions, but when trying to create in in the US with the exact same values etc I get the following response:

The item cannot be listed or modified. The title or description may contain improper words, or the listing or seller may be in violation of eBay policy.

I've tried removing all the html just leaving the bare descripive text in the center and I've tried changing the category ID (which is 360) with no real changes. Is there anything specific about this that you can see that might be banned in the US but not in Europe? i'm sure it can't be the item title since as I said its happening on multiple listings, and I've tried removing all but the bare minimum from the descriptions... Any help wowuld be much appreciated!
